I have stumbled upon the world of javascripting and css just moments ago and I have been given a project by my adviser on interactive maps.

The problem is I don't have a clue on how i should start this project and one thing I want to know and find out is that How can I make an interactive map with just javascript , css and a little bit of php or cms?

I would suggest doing a bunch of tutorials before jumping into a project like this. Get a feel for the language, then start with something simple. That said, the highlighting of the states that's happening there could be done with CSS.

@Cerbrus I have already practiced a lot of CSS styles and highlighting on hover but i don't quite get how i could put up an overlay on mouse over
